وَالَّذِينَ كَذَّبُواْ بِـَايَـتِنَا سَنَسْتَدْرِجُهُم مِّنْ حَيْثُ لاَ يَعْلَمُونَ
(Those who reject Our Ayat, We shall gradually seize them in ways they perceive not) meaning, the doors of provisions will be opened for them and also the means of livelihood, in this life. They will be deceived by all this and think that they are on the correct path. Allah said in another instance,
فَلَمَّا نَسُواْ مَا ذُكِّرُواْ بِهِ فَتَحْنَا عَلَيْهِمْ أَبْوَابَ كُلِّ شَىْءٍ حَتَّى إِذَا فَرِحُواْ بِمَآ أُوتُواْ أَخَذْنَـهُمْ بَغْتَةً فَإِذَا هُمْ مُّبْلِسُونَ - فَقُطِعَ دَابِرُ الْقَوْمِ الَّذِينَ ظَلَمُواْ وَالْحَمْدُ للَّهِ رَبِّ الْعَـلَمِينَ
(So, when they forgot (the warning) with which they had been reminded, We opened for them the gates of every (pleasant) thing, until in the midst of their enjoyment in that which they were given, all of a sudden, We took them (in punishment), and lo! They were plunged into destruction with deep regrets and sorrow. So the root of the people who did wrong was cut off. And all the praises and thanks are to Allah, the Lord of all that exists.)6:44-45. Allah said here,
وَأَمْلَى لَهُمْ
(And I respite them) prolong what they are in,
إِنَّ كَيْدِى مَتِينٌ
(certainly My plan is strong) and perfect.
Ma'arif al-Qur'an
Mufti Muhammad Shafi
The next verse (182) has provided answer to a common question which bothers the minds of many Muslims. If prosperity and progress can only be achieved by following the way of truth and justice why the non-Muslim nations of the world are seen more prosperous, more advanced and more powerful while they are very far from the truth? The verse answered this question in these words:
"As for those who belie our signs, we shall let them be drawn gradually towards (their punishment) from where they do not know."
That is to say, Allah does not punish those who reject the signs or verses of Allah immediately for their sins. He, out His wisdom and Mercy, lets them enjoy their worldly life for a while and then draws
them to their ignominious end as gradually as they do not know of their being led to their ill-fate. The present prosperity and progress of the non-Muslims should, therefore, not deceive people, because their
prosperity, in fact, is not something propitious for them. Rather it is a kind of respite, a temporary period of relief before the execution of their punishment, which in Qur'anic terminology is called Istidraj
Istidraj is a more powerful punishment in disguise. The most essential element of Istidraj is that a person is not punished for his evil deeds immediately; the more he increases in his evil deeds, the
more he is increased in prosperity and worldly possessions which prevents him from having a sense of guilty and taking warning against his crimes. Consequently, he is deprived of turning in repentance to Allah and save himself from everlasting punishment. This perverted state of mind makes one take illness as health and poison as remedy. He is let to go on with his perverted life until death overtakes him and draws him to the eternal chastisement.
The Holy Qur'an has made mention of 'Istidraj' in many other verses. It said in Surah al-An'-am:
فَلَمَّا نَسُوا مَا ذُكِّرُوا بِهِ فَتَحْنَا عَلَيْهِمْ أَبْوَابَ كُلِّ شَيْءٍ حَتَّىٰ إِذَا فَرِحُوا بِمَا أُوتُوا أَخَذْنَاهُم بَغْتَةً فَإِذَا هُم مُّبْلِسُونَ ﴿44﴾
"So, when they forgot what they were required to remember, We opened to them the gates of everything, until, when they were rejoicing in what they were given, We seized them suddenly, and then they were confounded in despair." (6:44)
Dealing with Istidraj is not limited to disbelievers only. The iniquitous among Muslims are also dealt with this kind of punishment. It was for this reason that our elders used to fear Allah when they were favoured by Him with prosperity and comforts. They feared lest their prosperity should be a sign of 'Istidraj'
The Truth is a thing which a man has to discover by himself. God has given everyone a heart (mind), eyes and ears. Man arrives at the Truth by utilizing these faculties. The man who does not do so will be unable to discover the Truth, howsoever close it may be to him. Discovery of the Truth is the conscious and deliberate act of every man. Only one who has kept the doors of his heart (mind) open for the purpose, will be able to understand the Truth. Only one who has not covered his eyes with artificial veils will be able to see it. Only one who has not plugged his ears will hear its voice. Such people will recognise the voice of Truth and will surrender themselves before it. And one whose case is opposite to this will remain mindless like the animals. It will not be possible for him to be moved by even the weightiest of arguments. Flashes of God’s brilliant light will appear before him, but he will not be able to see them. The melody of Divine song will come to his ears, but he will be prevented from hearing it. Truth is available to those who are awake; for neglectful people, no truth is Truth.
